Hi Ajk1,
Thank you for your post and welcome to the forums.
The hub would take any standard landline as it has a phone port on the back of the hub. Do you still have the packaging to the hub? As there would also be an adaptor - I hope this video sheds a little bit of light on how it's done.

Cheers.
